5 weeks post-op. Will this heal with wet to dry dressing as my surgeon recommends? (photo)

I had a tummy tuck muscle repair 5 weeks ago.At 3 weeks post op my incision in this area was splitting stitches. The nurse remove around 5 stitches in this area.It started out as one little hole from her digging around.My surgeon said do wet to dry dressing every 4 hours but now I have two holes it seems wet to dry is not helping.How would you handle the situation. Are the wet to dry really doing any good.
